How Much RAM Does a Soulmask Server Need?

Soulmask sits in a different weight class than most survival games when it comes to server resources. Before a single player connects, the server process is already consuming around 11-12GB of RAM. That is not a bug or a misconfiguration - it is just what the game costs to run, and understanding why helps you size things correctly from the start.

The reason it is so heavy comes down to the tribe AI system. In Soulmask, each player can recruit and manage up to 20 tribesmen NPCs, and the server is responsible for running pathfinding, task logic, and behavior state for all of them simultaneously. On a 15-player server where everyone has an active tribe, you are not just tracking 15 players - you could be running AI calculations for 200+ NPCs at the same time. Add buildings, crafting stations, storage containers, and world events on top of that, and the memory footprint adds up fast.

Player count alone is a poor predictor of how demanding your server will be. Tribe density, world age, and whether you are running mods all matter just as much, sometimes more.

The Baseline: What the Server Needs Just to Start

The Soulmask server process requires around 11-12GB of free RAM before anyone joins. That makes 16GB the hard floor - not a comfortable operating point, but the minimum needed to keep the process from failing at startup.

Running right at 16GB means you have 4GB or less of headroom for the operating system, player connections, active tribes, and anything else happening on the machine. That headroom disappears quickly. When a server runs out of available memory, the first signs are usually stutters during saves, slow inventory actions, and delayed crafting responses. If it gets worse, you will see the server crash or fail to write the save file cleanly - which means rollbacks or corrupted world data.

All WinterNode Soulmask servers start at 16GB of RAM. If you are planning a long-running world or have more than a handful of regular players, the guidance below will help you figure out whether stepping up makes sense for your situation.

Player Count and Tribe Load

The standard advice you will see elsewhere is something like “16GB for small groups, 24GB for medium, 32GB for large.” That is not wrong, but it skips the part that actually matters: NPC count is the real scaling variable, not player slots.

Here is why that distinction matters. Ten players with half-built bases and small tribes will put less pressure on the server than five players who have been at it for two months, each running maxed-out tribe rosters and sprawling compounds. The slot count on the server listing does not tell you much about the actual load.

With that framing in mind, here is how to think about the tiers:

16GB works for a small group of 5-10 players who are in the early-to-mid game, running modest tribe sizes, and not heavily modded. Expect this headroom to shrink as the world matures. If you notice save-related lag creeping in after a few weeks of play, the world has likely grown past what 16GB can comfortably hold.

24GB is the right target for most active private servers. This covers groups of 10-25 players comfortably, and it also covers smaller groups who are running large tribes, big builds, or have been playing long enough that the world state is substantial. If your regular sessions involve multiple full tribes doing raids, crafting, and base work simultaneously, this is where you want to be.

32GB is for larger communities pushing toward 50+ concurrent players, PvP servers where activity spikes are frequent and intense, or anyone running the server with a significant mod list. At 50 players with full tribe rosters, the server could be managing 1,000+ NPC entities at once. That is a lot of AI state to hold in memory, and 24GB starts to feel uncomfortably tight in those conditions.

World Age: The Creeping RAM Tax

This is the one that catches people off guard. A server that runs smoothly in week one can start showing strain by week four or five, without any change to the player count or configuration.

As your world matures, the memory footprint grows in several ways. Players explore more of the map, which means more chunks get generated and saved. Bases get bigger and fill up with storage containers holding thousands of items. Tribe rosters fill out. More crafting stations get placed and assigned to NPCs. All of that gets loaded into memory and kept there while the server is running.

We see this pattern in support tickets: someone sets up a 16GB server, everything feels fine for the first couple of weeks, and then performance starts degrading without any obvious cause. Nine times out of ten, the world has just grown past what the current RAM allocation can hold comfortably.

If you are planning a long-running world - anything you expect to still be playing two or three months from now - build in a buffer from the start. Upgrading after the fact works, but planning for headroom upfront is less disruptive than troubleshooting a sluggish server mid-season.

Mods

Soulmask supports Steam Workshop mods, and each one adds memory overhead. A couple of small cosmetic or quality-of-life mods will not move the needle much. A collection of script-heavy mods that add new mechanics, AI behaviors, or entity types is a different story.

As a rough guide: running 5 or more mods alongside an active player population, add 2-4GB of buffer to whatever you would otherwise allocate. Running 10 or more mods, especially on a server with 20+ players, pushes RAM needs solidly into 32GB territory.

One thing worth knowing: script-heavy mods can also affect save times, since more mod data gets written to disk on each autosave interval. If saves are taking longer than expected on a modded server, NVMe storage makes a real difference here - not just RAM.

Signs You Need More RAM

Rather than guessing, here are the observable symptoms that point specifically at memory pressure rather than CPU or other issues:

• Lag spikes that align with the autosave interval (every few minutes, the server hiccups)
• Slow or unresponsive inventory and crafting on an otherwise healthy server
• Server crashes that happen more frequently as the world gets older
• Save failures or rollbacks when the server shuts down unexpectedly

If you are seeing the first two, check whether reducing NPC limits in GameXishu.json helps before reaching for more RAM. Sometimes the issue is an NPC count that has grown beyond what the current allocation handles well. If reducing NPC limits does not help, or if you are running at the cap already, upgrading RAM is the right call.

WinterNode’s Soulmask server hosting is priced at $1.99/GB of RAM, with no extra charges for CPU usage, storage, or bandwidth. Stepping from 16GB to 24GB costs $15.92/month - no tier jumps or feature unlocks, just more RAM.

All game servers come with a 48-hour refund policy, so there is no risk in starting at one tier and adjusting from there. If you are not sure whether RAM or something else is the bottleneck, open a ticket - our support team can pull logs and work through the diagnostics with you before suggesting anything.
